I'm an avid Brightkite user, and a budding Foursquare user. To me, they both serve different purposes. For one, I like Brightkite because it's an okay place to start conversations. If I really want something to go to Twitter and Facebook, and to easily geo-tag my mobile photo uploads on Flickr, Brightkite is hard to beat. That said, I don't check in everywhere I go, and my check-ins are often vague. Cities or major intersections instead of actual addresses or venues. Of course, there are exceptions.
Generally, I only check in when I want people to know where I am, and it's often an invitation to come kick it with me. And if I check in to the same coffee shop every Monday, Wednesday and Friday morning, you'd bet I'd be glad to have you come up and and have a talk over a cup of joe if you "stalk" me and can predict where I'll be. Heck, I've met two people I consider great friends simply because we were checked in nearby on Brightkite and finally crossed paths.
It comes down to moderation. If you feel the need to check in every single time you move more than a few hundred feet in any given direction, you're probably OCD. Basically, I only check in if I plan on my situation becoming social.
